A method and system for occlusion region detection and measurement between a pair of images are disclosed. A processing device receives a first image and a second image. The processing device estimates a field of motion vectors between the first image and the second image. The processing device motion compensates the first image toward the second image to obtain a motion-compensated image. The processing device compares a plurality of pixel values of the motion-compensated image to a plurality of pixels of the first image to estimate an error field. The processing device inputs the error field to a weighted error cost function to obtain an initial occlusion map. The processing device regularizes the initial occlusion map to obtain a regularized occlusion map.

A guaranteed two-wire interface in which upon determining that an operation is to be performed on a slave component, a master component transmits at least a portion of a corresponding frame to the slave component over the data wire. The master component repeats this detection and transmission each time it determines that an operation is to be performed on a slave component, whether the same component or a different slave component as the slave component previously communicated with. The frame structure itself may change depending on the operation to be performed. For example, one frame might include an extended address data field that includes extended address information that goes beyond a basic address field included in another frame. One frame may include reliability fields (such as cyclic redundancy checking field, an acknowledgement field, and / or an error field), whereas another frame having a different operation may not.

Systems, methods, and computer program products for enabling assessment of the quality of a search index. In one embodiment, objects are processed to produce corresponding text that is stored and indexed. The objects are also processed to identify and store corresponding metadata values for indexing. Error conditions that are detected during the processing of objects to generate corresponding text are tracked and compared to determine the most severe of the error conditions. An indication of the most severe error condition is stored in a first consolidated error field. Errors that are encountered in the identification and storage of metadata values are counted and this count is stored in a second consolidated error field. Both of the consolidated error fields are indexed in the same manner as the text and metadata for the objects, so that the stored error information can be used in queries of the search index.

An interlaced image processing module and corresponding method facilitate improved processing of interlaced motion images. In one embodiment, the interlaced image processing module receives image data frames having interlaced first and second fields and produces a reference field and error field. The reference field corresponds to the still image content of the interlaced frame, whereas the error field corresponds to the motion content of the interlaced frame, particularly the motion between fields. Motion between fields is thus represented in the error field, without redundant representation of the still image content provided by the first field. Where there is little motion between fields, the error terms will be small so the predictor preserves the coding efficiency provided by any auto-correlation in the image. Further, the interlaced image processing method does not rely upon pixel group classification, and thus avoids classification errors, and the loss of coding efficiency from still image content in motion classified blocks. Finally, problems presented by relative motion between fields are avoided, as are local artifacts. Another embodiment transforms the interlaced fields into frame data having a high frequency field and a low frequency field.

An apparatus, method, and system for providing a fine adjustment for transducing head positioning in a hard disk drive (HDD). The apparatus, method, and system include reading a positioning error field wherein the resulting signal is a substantially sinusoidal position error signal (PES), filtering the PES to remove low frequencies and attenuate high frequencies, sample the filtered PES at a multiple of the channel frequency, filter the higher frequency harmonics, down sample the PES, and provide a signal proportional to the amplitude of the down sampled PES. This signal is the reference signal to the head positioning servo.

The invention discloses a three-dimensional measurement system and three-dimensional measurement method for a steel plate with lasers and vision combined. The system is mainly composed of two background projectors, a total station, a three-dimensional scanner and a GPU server. The background projectors, the three-dimensional scanner and the total station are all connected to the server. The method comprises the steps that a plurality of laser labels are placed around the steel plate to be measured; the lasers are used for measuring the three-dimensional coordinates of the labels, and two cameras in the three-dimensional scanner are used for shooting the laser labels; an HOG and an SVM are used for detecting the original positions of the labels; a DOG is used for precisely locating the center of the labels; the three-dimensional coordinates of the labels are measured, the coordinates are converted into a laser coordinate system from a visual system, the errors of a calculation sum are obtained, and an error field is constructed; the scanner is used for measuring the steel plate to be measured to obtain the three-dimensional data of the steel plate; the error field is used for correcting the three-dimensional data of the steel plate to obtain the more accurate three-dimensional data of the steel plate. Laser measurement and vision measurement are combined, and the errors of the vision measurement can be greatly reduced.
